Potassium Hydroxide → 3,3,4,4-Tetrafluoro-4-iodo-1-butene

Participants

Reaction Steps

the 1,4-diiodo-1,1,2,2-tetrafluorobutane reacting with at least a stoichiometric amount of potassium hydroxide or sodium hydroxide in the form of an approximately 10 to 60% strength by weight aqueous solution at a temperature of 20° to 100° C. and in the presence of a phase transfer catalyst in an amount of 0.1 to 5 mol %, relative to the amount of 1,4-diiodo-1,1,2,2-tetrafluorobutane, to eliminate hydrogen iodide, and isolating 1-iodo-1,1,2,2-tetrafluoro-3-butene from this reaction product,
